Michigan Permit Supervisor Rules: Age 21, Front Seat, Written Auth

To drive with a Michigan Level 1 Learner's License, you must be supervised by a licensed parent, legal guardian, or designated licensed adult aged 21 or older.

What Are Michigan Level 1 Supervisor Age, License, and Seat Requirements?

Michigan requires the supervisor of a Level 1 driver to be at least 21 years old, hold a valid Michigan or equivalent driver license, and sit in the front passenger seat on every drive. A licensed adult in the back seat does not satisfy the supervision requirement under MCL 257.310e.

Under MCL 257.310e, the supervisor must be 21 or older, hold a valid unsuspended license, sit in the front passenger seat, and be unimpaired. Non-parent supervisors require a signed parental designation letter.

Under Michigan GDL law (MCL 257.310e), your supervisor is legally responsible for the vehicle.

• Age Requirement: The supervisor must be 21 years of age or older.
• License Status: They must hold a valid, unexpired license with no current suspension or revocation. A suspended or expired license disqualifies them.
• Seating Position: The supervising adult should sit in the front passenger seat, ready to assist with vehicle operation.
• Sobriety: Michigan law requires the supervising adult to be fit to drive and not impaired by alcohol or drugs. Any detectable impairment can lead officers to treat it as driving unsupervised.
• Parental Authorization: If the supervisor is not your parent or guardian, they must be designated by your parent with a signed, dated authorization letter naming each designated supervising adult age 21 or older.

Who Legally Qualifies to Supervise a Michigan Level 1 Driver?

Parents, grandparents, legal guardians, adult siblings who are 21 or older, and any licensed adult who meets the age requirement qualify as supervisors. A 20-year-old sibling with a full license does not qualify. An 18-year-old parent does not qualify regardless of license status.

Licensed parents, legal guardians, designated adults 21 or older, and certified driving instructors. A licensed sibling who is 20 years old does not qualify: the cutoff is 21, no exceptions.

Only licensed parents, guardians, designated 21-plus adults, or certified instructors can sign off practice time on the official Michigan supervised driving log (SOS-191).

Hours with anyone else do not count toward your required 50 practice hours.

Supervisor Violations and the GDL Clock Reset They Trigger

If an officer finds a Level 1 driver without a qualified supervisor, both the driver and the adult present can be cited. The driver receives a misdemeanor charge and two points. The 90-day violation-free window resets to day zero. Repeat violations can delay Level 2 eligibility by six months or more.

Any conviction, at-fault crash, or license sanction within 90 days of a Level 2 application restarts the 90-day clean-period clock. Supervisor disqualification can void logged practice hours.

Violations or at-fault crashes can extend the required 90-day clean period under the graduated licensing statute.

If a Level 1 driver gets any conviction, at-fault crash, or license sanction within 90 days of applying for Level 2, the examiner cannot approve the upgrade until a new 90-day violation-free period is completed.

• Supervisor Age Confusion: A learner in Grand Rapids was cited after driving with their 20-year-old licensed brother. The Lansing SOS office rejected their Level 2 application, requiring a new 90-day wait.
• Out-of-State License Issue: A supervisor from Ohio had a valid license but was cited for a broken taillight. The trooper discovered an old suspension on their Ohio record, making them ineligible. The practice hours were voided.
• Sobriety Misunderstanding: A parent in Ann Arbor thought one beer was under the legal limit. During a routine stop, the officer detected impairment. The teen was cited for driving unsupervised, adding months to their permit phase.

How Do You Document Michigan Permit Supervision to Protect Your Driving Log?

Log each practice session with the supervisor's name, license number, date, time, duration, and road conditions on Form SOS-383. A co-signed log protects you if a road test examiner questions any entries. Keep the completed log in a folder with your permit for every road test appointment.

Verify your supervisor's license status before logging hours to avoid entire driving log rejection.

• Verify your supervisor's license status online before logging hours to avoid having your entire driving log rejected at the Southfield SOS branch.
• Print and carry a parent designation letter for any non-guardian supervisor to prevent a 30-minute traffic stop verification that could make you late for your road test appointment.
• Complete your driving log digitally as you go and get it signed weekly to avoid the last-minute scramble and missing hours that causes rescheduling at busy offices like the one in Sterling Heights.

If you lack a supervisor, you can take lessons with a teen-certified driver education provider, and those supervised hours may be counted toward the required 50 logged hours if recorded on the supervised driving log.
